J. R. Forster#R, 1781,
Until recently considered conspecific with Z. mauritianus. Very variable in colour, proportions and genetics over short distances#R, with three monomorphic populations in lowlands and a polymorphic (brown and grey) one in highlands#R, and evidence that highland and lowland groups diverged in allopatry#R, although morphs have no genetic signature and are presumed to be recent developments#R. Two subspecies have been named, alopekion and xerophila, from near sea level and uplands, but are no longer generally recognized. Monotypic.
Introduced, unsuccessfully, to Île Sainte-Marie (off NE Madagascar) and Nosy Be (off NW Madagascar) in 19th century#R.
